[0002] The railway height limit protection frame is usually a steel structure installed on both sides of the railway bridge culvert with a height of less than five meters. Its function is to prevent vehicles from colliding with the railway bridge and causing damage to the foundation of the railway line. It plays a good protective role in the normal operation of the railway above the railway culvert.

[0003] However, when the existing intelligent anti-collision railway height limit guardrail is in use, it is usually unable to give early warning and intercept super-high vehicles, so that the super-high vehicles are not aware of it until they are stopped by the guardrail when they drive to the guardrail, resulting in the super-high vehicles being easily caught in a dilemma at the guardrail, and also causing interference to subsequent vehicles that need to pass through the guardrail; in addition, when the existing railway height limit guardrail is installed, it is usually set on both sides of the curb of the highway, and because the roadbed of some highways is narrow, the bottom end of the guardrail occupies the position within the curb when it is erected, and the height limit guardrail that suddenly appears on the highway is easy to interfere with the vehicles running close to the curb, causing the bottom end of the railway height limit guardrail to be easily rubbed or hit by the vehicles running close to the curb, affecting the normal use of the guardrail.

[0023] like Figures 1 to 4As shown, the intelligent anti-collision railway height limit protection frame of this embodiment includes a gantry 2, which is composed of a hollowed-out horizontal beam and two vertical beams, so that the control module 12 can be installed in the gantry 2, and the rolling steel plate 6 can also be stored in the gantry 2 when not in use, to ensure that vehicles below the height limit frame can pass smoothly, and an audible and visual alarm 1 is fixedly installed on the top of the gantry 2. After receiving the signal, the audible and visual alarm 1 can emit an alarm sound and flashing lights to give advance warning to the vehicle in front of the height limit protection frame, and a rolling steel plate 6 is arranged inside the gantry 2, and the rolling steel plate 6 is a rolling steel plate composed of multiple steel plates flexibly connected. The rolling shutter steel plate 6 has a rolling shutter door structure, which can be rolled up or unfolded to open and close the hole enclosed by the gantry 2, and the rolling shutter steel plate 6 can form a rolling shutter door structure with the gantry 2 when it is lowered, so as to intercept vehicles that exceed the height limit. The bottom end of the rolling shutter steel plate 6 is fixedly connected with a cross bar 7, which is made of metal material and has a heavy quality. The unfolded rolling shutter steel plate 6 can be straightened to facilitate the rolling shutter steel plate 6 to fall along the gantry 2. At the same time, the anti-collision ability of the rolling shutter steel plate 6 can also be increased to intercept over-height vehicles that break in. A moving character screen 5 is installed on the front of the gantry 2. The moving character screen 5 is an LED screen. After detecting an over-height vehicle, the over-height vehicle can be intercepted. The vehicle is reminded by text to avoid excessive behavior by the vehicle driver. A laser sensor 4 is fixedly installed at the bottom of the front of the gantry 2. The detection distance of the laser sensor 4 is within five meters. When the roof of the super-high vehicle is detected by the laser emitted by the laser sensor 4, the control module 12 is triggered to control the rotating motor 3 and other structures, so that the super-high vehicle can be reminded when it is five meters away from the protective frame, avoiding the situation where the super-high vehicle is stuck when it drives to the protective frame, thereby reducing the blockage of vehicles at the protective frame. The control module 12 is installed on the top of the inner side of the gantry 2, and the two sides of the bottom of the gantry 2 are fixedly connected with side blocks 8 The side block 8 is a square structure, which can play a role in reinforcing the bottom end of the gantry 2. A card frame 10 is fixedly connected to the front of the side block 8. The card frame 10 is a hollow structure. A plurality of rollers 9 are arranged inside the card frame 10. The diameter of the roller 9 is greater than the width of the card frame 10, so that the outer wall of the roller 9 can protrude out of the card frame 10, which is conducive to the roller 9 being fitted by the vehicle. A plurality of empty cylinders 14 are fixedly connected to the outer wall of the roller 9. A cavity is opened inside the empty cylinder 14, and the empty cylinder 14 is a metal structure. A plurality of round balls 15 are movably embedded inside the empty cylinder 14. The round balls 15 are also a metal structure, so that the round balls 15 can make a metallic sound when they shake and collide in the empty cylinder 14.

[0024] Specifically, a rotating motor 3 is fixedly installed on the top of one side wall of the gantry 2, and a rotating column 11 is engaged with the output end of the rotating motor 3. The rolling shutter steel plate 6 is movably connected to the rotating column 11. After the rotating motor 3 is connected to an external power supply, it can drive the rotating column 11 to rotate, thereby driving the rolling shutter steel plate 6 to unfold, so that the rolling shutter steel plate 6 can fall along the gantry 2 to intercept overheight vehicles.

[0025] Furthermore, the sound and light alarm 1, the laser sensor 4, the scrolling screen 5 and the rotating motor 3 are all electrically connected to the control module 12. After receiving the signal transmitted by the laser sensor 4, the control module 12 controls the sound and light alarm 1, the scrolling screen 5 and the rotating motor 3 to run simultaneously, thereby enhancing the height limit reminder of the height limit protection frame.

[0026] Furthermore, sliding grooves 13 are provided on the inner walls on both sides of the gantry 2, and the two ends of the cross bar 7 are respectively slidably connected to the sliding grooves 13. The sliding of the cross bar 7 along the sliding grooves 13 can maintain the stability of the cross bar 7 when sliding in the gantry 2, and at the same time can make the rolling steel plate 6 more stable when lowering.

[0027] Furthermore, an opening is provided at the top of the gantry 2, and the rolling shutter steel plate 6 is movably connected to the gantry 2 through a rotating column 11 and a cross bar 7. The rolling shutter steel plate 6 passes into and out of the top of the gantry 2 through the opening, so that the rolling shutter steel plate 6 can be stored in the gantry 2 for protection when not in use, thereby extending the service life of the rolling shutter steel plate 6.

[0028] Furthermore, a rotating rod 16 runs through the middle of the drum 9, and the rotating rod 16 is rotatably connected to the card frame 10. The drum 9 is rotatably connected to the card frame 10 through the rotating rod 16. The rotating rod 16 can make the drum 9 more stable when rotating in the card frame 10, thereby improving the anti-collision ability of the height limit protection frame.

[0029] Furthermore, the card frame 10 is fixedly connected to the gantry 2 through the side block 8. The side block 8 can wrap the bottom end of the gantry 2 to increase the anti-collision ability of the gantry 2. At the same time, the side block 8 can be disassembled to facilitate the replacement of the damaged side block 8 and the card frame 10.

[0030] The method of using this embodiment is as follows: when installing the intelligent anti-collision railway height limit protection frame, it is necessary to make the gantry 2 and the side walls of the card frame 10 on the same horizontal line, and then the protection frame needs to be connected to an external power supply or equipped with solar panels for power supply, so that the electrical components on the protection frame can operate normally. When a vehicle that exceeds the height limit of the protection frame travels to a distance of five meters directly in front of the gantry 2, it will be detected by the laser sensor 4 fixedly installed on the top of the gantry 2, and then the laser sensor 4 will feed back the signal to the control module 12, at which time the control module 12 will control the rotating motor 3, the sound and light alarm 1 and the scrolling screen 5 to start, and at this time the sound and light alarm 1 will emit an alarm sound and flashing lights, and at the same time the scrolling screen 5 will have "You are too high, please do not pass" ” is a scrolling subtitle for text reminder, and the rotating motor 3 will drive the rotating column 11 to rotate, drive the rolling steel plate 6 to unfold and be straightened by the cross bar 7, and then slide downward along the slide groove 13 in the gantry 2 to block the hole of the gantry 2, so that the gantry 2 forms a closed gate to intercept super-high vehicles. When a vehicle is about to rub against the inner wall of the gantry 2, it will first fit and rub against the roller 9 on the card frame 10, so that the roller 9 rotates along the rotating rod 16 to reduce the impact force brought by the vehicle. At the same time, the ball 15 in the empty cylinder 14 on the outer wall of the roller 9 will shake in the empty cylinder 14 and continuously collide with the inner wall of the empty cylinder 14, making a metallic rustling sound, giving a voice reminder to the vehicle driver, so that the vehicle is not easy to rub against the bottom end of the gantry 2.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
